0–100, higher is better. How it is calculated

Valve Corporation operates a professional and well-structured website focused on game development, the Steam digital distribution platform, and hardware products. The site demonstrates a mature digital presence with multimedia content, job listings, and clear navigation. The use of Akamai CDN and Google reCAPTCHA indicates a modern technical infrastructure. Security posture is solid with HTTPS and security policy pages, though some improvements such as explicit security headers and cookie consent mechanisms are recommended. The absence of WHOIS data is a notable anomaly but does not detract from the overall legitimacy indicated by the website content and external partner links. Overall, the site presents a trustworthy and professional front for a major technology company.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Valve holds a leading position in the gaming and digital distribution market, leveraging its Steam platform as a core revenue and service channel. The company employs a flat organizational structure and hires experts across diverse fields including software engineering, hardware, game design, and business development. The business model combines product development with platform services, targeting gamers, developers, and partners globally. The partnership ecosystem includes official Steam partner sites and storefronts, reinforcing its market reach. Growth indicators include ongoing job postings and hardware initiatives. The company maintains a strong brand with consistent messaging and professional digital assets.

Security posture

Valve's website security posture is robust with enforced HTTPS and use of Google reCAPTCHA to protect forms. The presence of a dedicated security page indicates awareness and commitment to security practices. However, the lack of explicit security headers such as Content-Security-Policy and absence of a published vulnerability disclosure or security.txt file represent areas for improvement. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information is not publicly available, which could hinder rapid communication in case of security events. Overall, the security maturity is good but could be enhanced with additional transparency and technical controls.

Recommendations

  1. Implement and publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  2. Add explicit security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve defense-in-depth.
  3. Deploy a cookie consent banner to comply with GDPR and enhance privacy compliance.
  4. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  5. Investigate and resolve the missing WHOIS data to improve domain registration transparency and trust.

Technical notes

Notes

The website uses a stable and mature technology stack including jQuery 1.8.3 and Google reCAPTCHA for bot protection. Multimedia content is delivered efficiently via Akamai CDN, ensuring fast load times and good performance. The site is mobile optimized with responsive design and uses HTML5 video elements for rich media. SEO is supported by comprehensive meta tags and Open Graph data. Accessibility is basic but functional. No CMS or major frameworks were detected, indicating a custom or lightweight implementation. Technical risks include reliance on an older jQuery version and lack of advanced security headers. Overall, the technical infrastructure supports a high-quality user experience with room for modernization.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
